Munzvimbo yeinjiniya yezvimiro, kutsvakwa kwezvinhu uye magadzirirwo anowedzera mashandiro uye kusimba kwezvinhu zvekuvaka kuri kuenderera mberi. Ongororo ichangoburwa yakavheneka nezve axial compression performance yekongiri-yakazadzwa kaviri-ganda machubhu (CFDST) yakasimbiswa nekabhoni fiber reinforced polymer (CFRP). Iyi nzira yekuvandudza inonyanya kukosha kumakambani akaita seTianjin Reliance Steel, iyo inoshanda mukugadzira masikweya uye rectangular simbi chubhu, kusanganisira SHS (Square Hollow Sections) uye RHS (Rectangular Hollow Sections). Ichi chinyorwa chinotarisa mune zvakawanikwa muchidzidzo, zvinorehwa neindasitiri yekuvaka, uye kuti Tianjin Reliance Steel yakamisikidzwa sei kuti isangane nezviri kubuda zvinodikanwa zvezvimiro zvekushandisa.
Kunzwisisa Concrete-Filled Double-Skinned Tubes (CFDST)
Concrete-yakazadzwa kaviri-ganda machubhu chinhu chinoumbwa chiumbwa chinosanganisa zvakanakira simbi uye kongiri. Iyo yekunze simbi chubhu inopa kuvharirwa kune kongiri musimboti, ichiwedzera kumanikidza kwayo simba uye ductility. Iyi dhizaini inonyanya kubatsira munzvimbo dzinowanzoita seismic, uko zvimiro zvinofanirwa kushingirira akakosha lateral masimba. Chidzidzo chiri mukutarisa chinoongorora makoramu gumi neshanu eCFDST, imwe neimwe iine akasiyana eCFRP ekusimbisa zvirongwa, kuongorora mashandiro avo axial compression.
Basa reCFRP mukusimbisa Kwemaitiro
Carbon fiber reinforced polymer (CFRP) chinhu chakareruka, chakasimba-chakasimba icho chakawana mukurumbira mumashandisirwo ezvimiro nekuda kwekunaka kwemakanika ezvivakwa uye kuramba kushatiswa kwezvakatipoteredza. Nekubatanidza CFRP mukugadzirwa kwemakoramu eCFDST, mainjiniya anogona kuvandudza zvakanyanya kutakura mutoro uye kuita kwese kwezvivakwa izvi. Chidzidzo ichi chinoongorora zvirongwa zvakasiyana-siyana zvekusimbisa, zvichiongorora kuti masisitimu akasiyana eCFRP anogona kukwirisa sei axial compression kuita kwemakoramu.
Zvakawanikwa Muchidzidzo chacho
Tsvagiridzo inoburitsa zvakati wandei zvakakosha zvakawanikwa maererano neaxial compression kuita kweCFRP-yakasimbiswa CFDST makoramu:
- Kuwedzerwa Kutakura-Kutakura Kukwanisa: Iko kubatanidzwa kweCFRP kusimbiswa kunowedzera zvakanyanya simba rekutakura mutoro weCFDST columns. Chidzidzo ichi chinoratidza kuti zvirongwa zvekusimbisa zvakanangana zvinogona kutungamira mukuvandudzika kwekuita kana zvichienzaniswa nemachubhu akazadzwa nekongiri.
- Ductility uye Energy Absorption: Iyo CFRP yekusimbisa haingo wedzera simba asiwo inovandudza ductility yemakoramu. Hunhu uhu hwakakosha mukuita seismic application, uko zvimiro zvinofanirwa kutora nekubvisa simba panguva yekudengenyeka kwenyika.
- Kukundikana Modes: Chidzidzo chacho chinozivisa nzira dzakasiyana dzekukundikana kweCFRP-yakasimbiswa CFDST makoramu, ichipa ruzivo rwakakosha pamabatiro anoita zvimiro izvi pasi peaxial mitoro. Kunzwisisa nzira idzi dzekutadza kwakakosha pakugadzira zvimiro zvakachengeteka uye zvakanyanya kusimba.
- Optimal Reinforcement Schemes: Nekuenzanisa akasiyana maCFRP ekusimbisa masisitimu, tsvakiridzo inotaridza zvirongwa zvakakwana zvinowedzera kuita uku uchideredza kushandiswa kwezvinhu. Ichi chiwanikwa chakanyanya kukosha kune zvinodhura maitiro ekuvaka.
Zvinorehwa neIndasitiri Yekuvaka
Zvakawanikwa zvechidzidzo ichi zvine zvazvinoreva kune indasitiri yekuvaka, kunyanya mukugadzira uye kuita zvinhu zvemagadzirirwo muzvivakwa zvepamusoro-soro, mabhiriji, uye zvimwe zvakakosha zvivakwa. Iko kukwidziridzwa kwekuita kweCFRP-yakasimbiswa CFDST makoramu kunogona kutungamirira kune yakachengeteka, yakawedzera kusimba zvivakwa zvakashongedzerwa zvirinani kutsungirira matambudziko anokonzerwa nenjodzi dzinongoitika dzoga uye mitoro inorema.
Zvakare, kugona kukwirisa zvirongwa zvekusimbisa zvinobvumira mainjiniya kugadzira zvimiro zvisina kusimba chete asiwo zvine hupfumi. Izvi zvinonyanya kukosha munguva iyo kusimba uye kudhura-kushanda kwakakosha mukuita zvekuvaka.
Tianjin Reliance Simbi: Mutungamiriri muStructural Solutions
Semugadziri ane mukurumbira wemachubhu ane sikweya uye rectangular simbi, anosanganisira SHS neRHS, Tianjin Reliance Steel yakanyatso kurongeka kuti iwane mari mukufambira mberi kweCFDST tekinoroji. Kuzvipira kwekambani kune mhando uye hunyanzvi hunoenderana nezvakawanikwa muongororo ichangoburwa, zvichiita kuti vape mhinduro dzemhando yepamusoro kune vatengi vavo.
Tianjin Reliance Steel's product range inosanganisira akasiyana simbi chubhu profiles inogona kushandiswa mukuvaka kweCFDST makoramu. Nekubatana nevainjiniya nevagadziri vezvivakwa, kambani inogona kupa mhinduro dzakagadzirirwa dzinosanganisira kusimbiswa kweCFRP, kuve nechokwadi chekuti zvigadzirwa zvavo zvinosangana nezvinodiwa zvezvirongwa zvekuvaka zvemazuva ano.
Mhedziso
Kuongororwa kweaxial compression performance muCFRP-yakasimbiswa kongiri-yakazadzwa kaviri-ganda machubhu inomiririra kufambira mberi kwakakosha muinjiniya yezvimiro. Zvakawanikwa muchidzidzo ichi zvinosimbisa kugona kwezvinhu izvi zvakaumbwa kuti zviwedzere kuchengetedzeka, kusimba, uye kugona kwezvinhu zvekuvaka. Sezvo indasitiri iri kuramba ichishanduka, makambani akaita seTianjin Reliance Steel akagadzirira kutungamira nzira mukupa zvigadziriso zvinosangana nezvinodiwa nemapurojekiti ezvivakwa zvemazuva ano. Nekugamuchira matekinoroji matsva uye zvekushandisa, chikamu chekuvaka chinogona kuvaka ramangwana rakatsiga, rinokwanisa kumirisana nematambudziko emangwana.
